Abstract
A kind of fishing tool logging in sundries in dilatory drill for submarine pipeline Directional Drilling, it include: admission extinguisher, the anti-lost spiral being mounted in admission extinguisher internal cavities, the connection screw thread for being mounted on admission extinguisher one end, wherein, admission extinguisher is closed at one end, the shape of falling η open at one end, connection screw thread are mounted on the closed end bottom of admission extinguisher.The utility model can not only portal the salvagings such as stone, iron filings, abrasion components in directional drilling, solve the problems, such as to fall sundries salvaging in directional drilling；It can also enough preventing in submarine pipeline heave, sundries is destroyed caused by submarine pipeline erosion resistant coating, ensure that the integrality of erosion resistant coating when extra large pipe logs in.
Description
Technical field
The utility model relates to submarine pipeline, more particularly to it is a kind of logged in for submarine pipeline Directional Drilling it is miscellaneous in dilatory drilling
The fishing tool of object belongs to Offshore Engineering equipment field.
Background technique
Currently, submarine pipeline, which logs in dilatory operation, generally drags method and bottom tow method pull technology using floating, submarine pipeline is led to
Cross dilatory logged in.Both the above submarine pipeline login method, can satisfy most of undersea pipe-laying logs in environment
Condition.But when the submarine pipeline for being related to logging in is more, submarine pipeline logs in construction space is insufficient, submarine pipeline logs in
Position have the barrier that can not go beyond, submarine pipeline login location it is stringent to environmental protection requirement when, above-mentioned two kinds of methods, just not
Be able to satisfy submarine pipeline logs in requirement.
To solve the above-mentioned problems, after carrying out positioning drilling, reaming, borehole cleaning in submarine pipeline using directional drilling machine,
Submarine pipeline is carried out back again to drag technology, solves the problems, such as that submarine pipeline can not log in.But it is miscellaneous when being fallen in directional drilling
When object, and there is sundries and can not salvage the technical problem portalled, is easy to damage to the erosion resistant coating of submarine pipeline.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and provide and be used for submarine pipeline
Directional Drilling logs in the fishing tool of sundries in dilatory drill, can not only be by stone, iron filings, abrasion components in directional drilling
Equal salvagings are portalled, and solve the problems, such as to fall sundries salvaging in directional drilling；It can also enough preventing from drawing in submarine pipeline
Cheng Zhong, sundries are destroyed caused by submarine pipeline erosion resistant coating, ensure that the integrality of erosion resistant coating when extra large pipe logs in.
The purpose of this utility model is realized by the following technical solutions:
A kind of fishing tool logging in sundries in dilatory drill for submarine pipeline Directional Drilling, it is characterised in that: include: to receive
Receive cylinder, be mounted in admission extinguisher internal cavities anti-lost spiral, be mounted on the connection screw thread of admission extinguisher one end, wherein admission extinguisher
To be closed at one end, the shape of falling η open at one end, connection screw thread is mounted on the closed end bottom of admission extinguisher.
The anti-lost spiral is piece shape spiral.
The utility model has the beneficial effects that the utility model is due to the adoption of the above technical scheme, can not only will orient
The salvagings such as stone, iron filings, abrasion components are portalled in drilling, and solve the problems, such as to fall sundries salvaging in directional drilling；Moreover,
It can also prevent in submarine pipeline heave, sundries is destroyed caused by submarine pipeline erosion resistant coating, ensure that extra large Guan Denglu
When erosion resistant coating integrality.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Major Symbol illustrates in figure:
1. anti-lost spiral, 2. admission extinguishers, 3. connection screw threads.
Specific embodiment
As shown in Figure 1, the utility model is included: admission extinguisher 2, is mounted on 2 internal cavities of admission extinguisher by the way of welding
In anti-lost spiral 1, using the connection screw thread 3 for being threadably received in 2 one end of admission extinguisher, wherein admission extinguisher 2 be one end
Closing, the shape of falling η open at one end, connection screw thread 3 are mounted on the closed end bottom of admission extinguisher 2.
Above-mentioned anti-lost spiral 1 is piece shape spiral.
In use, connection screw thread 3 is mounted on drilling rod front end, drilling machine, which rotates forward to drive, salvages bucket rotation, under be drilled into it is miscellaneous in hole
Object location is gradually rotated sundries to admission extinguisher 2 by anti-lost spiral 1, realizes the purpose for removing sundries.By repeatedly beating
Fishing, the eliminating impurities in drilling are clean, it prevents subsequent drilling from bit freezing occurs, damages equipment.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
Claims (2)
